Percent error Calculatrice

Percent error calculation

The absolute error is equal to the absolute Valeur of the difference between the exact value and the approximated value:

ε = | V_exact - V_approx |

The percent error is equal to the 100% times the absolute error divided by the exact Valeur:

δ = 100% × | V_exact - V_approx | / | V_exact |
